The present invention relates to new and useful improvements in window constructions and more particularly to a metal frame and sliding sash.

An important object of the present invention is to provide resilient guide channels for the side edges of the sash and in which theedges of the channels have adjustable friction grippin en.- gagement with the edges of the sash to hold the sash in vertically adjusted position without requiring the use of sash cords or other counterbalancing means for the sash. I 3

Another object of the invention is to construct the sash of spaced parallel panes to provide a dehydrated air space therebetween as an insulating means for the sash without necessitating the use of a storm sash.

A still further object is to provide a novel screen hanger and screen frame construction for use in conjunction with. the metal window frame.

A still further object is to provide a device of this character of simple and practical construction, which is efficient and reliable in use, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the .details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a front elevational view showingthe upper and lower sash removed from the window frame;

Figure 2 is an enlarged vertical sectional view through the sash and window frame and also showing the screen in vertical section secured to the outside of the frame;

Figure 3 is an enlarged sectional view taken substantially on the line 33 of Figure 1;

Figure 4 is a fragmentary sectional View of the sash frame showing the groove therein for slidable engagement with the channel;

Figure 5 is a fragmentary sectional view taken on a line 5-5 of Figure 1, and;

Figure 6 is a fragmentary transverse sectional view taken on a line 6-6 of Figure 2 and showing the sash lock.

Referring now to the drawings in detail Wherein for the purpose of illustration I have disclosed a preferred embodiment of the present invention the numeral 5 designates a metal window frame which includes a metal sill 6 and metal header I. The head I is formed with a stepped portion 1 Claim. (Cl; 1891-72) 2 I V 8 to provide a raised outer portion to receive the upper edge of th upper sliding sash 9.

The upper sliding sash 9 and lower sliding sash II] are constructed of spaced parallel panes II secured in spaced parallel relation to each other and sealed at their edges by a suitable plastic spacing strip I2 to provide a dehydrated air space between the panes. The edges of the panes are cemented or otherwise suitably secured in a channel-shaped sash frame I3 of an suitable metal.

The side edges of the upper and lower sash are slidably received in channel-shaped sash guides I4 of resilient metal construction and secured in vertical position at the sides of the frame 5 by screws I5.

The outer edges of the flanges of the sash guides I4 are bent inwardly in opposed relation with respect to each other to form lips as shown at I6 and are slidably received in verticalfgrooves' ll in the sides of the sash frames I3. The base or Web portions l8 of the channels I4 are convexed in a transverse direction to space the longitudinal central portion of the base of the channel-shaped guides I4 from the side of the frame 5 whereby a tightening of the screws I5 will close the inwardly projecting lips l6 of the channel guides toward each other to thus regulate a friction gripping engagement thereof in the grooves ll of the frame with the sash to thus suitably bind the sash in the guides and hold the sash in a vertically adjusted position in the frame without necessitating the use of sash cords or other counter-balancing means for the sash. The adjusting action of the channels I4 is indicated b dotted linesin Figure 3, wherein it will be observed that by pressing the convexed web portion I8 inwardly by the tightening of the screws I5, and since the angle of the flanges l4 relative to the Web portion has a tendency to remain constant, the lips I6 of the flanges will be moved toward each other to seat more tightly in the grooves I! of the sash.

Metal weather stripping I9 is secured to the stepped portion 8 of the header 1 of the window frame for engagement by the upper edge of the upper sash 9 and metal weather stripping 20 is also secured to the sill 6 for engagement by the lower edge of the lower sash I I]. The opposed sides at the bottom of the upper sash 9 and at the top of the lower sash Ill are also provided with interlocking metal weather stripping 2| of conventional construction.

The sash is locked in a closed position by means of a spring projected bolt 22 slidably carried in the frame I3 at the upper edge of the lower sash and with its outer end arranged for entering an opening 24 in a block 25 suitably secured to the lower frame of the upper sash 9 as shown in Figure 2 of the drawings.

The lower edge of the upper sash 9 is provided with a handle 26 to facilitate raising and lowering thereof and the lower inner edge of the lower sash I is also provided with an angular lift bar 21 suitably secured thereto.

I also provide a screen designated generall at 28 for use in conjunction with the metal window frame 5, the upper edge of the screen being secured between inner and outer rigid metal clamping strips 29 and 30 secured to each other with the screening clamped therebetween by screws or the like 3 I. The inner strip 29 is of substantially shallow channel-shaped construction and the lower edge of the outer strip 30 is bent inwardly as shown at 32 to enter the channel between the upper and lower flanges 33 and 34 of the strip 26 to effectively bind the screen therebetween.

The outer strip 30 is likewise of substantially shallow channel-shaped construction on which the lower inwardly bent edge 32 forms the lower flange and'the upper flange 35 extends upward- 1y above the inner strip 29 for bearing against the outer surface of the head 7 of the window frame. The strip 30 is formed with one or more openings 36 to receive outwardly projecting hanger hooks 3T welded or otherwise suitably secured to the head 1.

The lower edge of the screen is similarly clamped between inner and outer clamping strips 33 and 35 secured to each other by screws or the like 40, the inner clamping strip having an inwardly projecting flange 4| at its upper edge through which a screw 42 is inserted for threaded engagement in the upper flange 43 of a channelshaped bracket 44 welded or otherwise secured to the sill 6.

The outer clamping strip 39 is of shallow channel-shaped construction with its lower flange 45 bearing against the outer surface of the sill 6 and its upper flange 46 bearing against the inner strip 38. The strip 39 is also provided with one or more openings 41 for receiving the outwardly projecting hooked lower flange 48 of the bracket 44.

The side edges of the screen 28 are loose to bear against the outer side edges of the frame 5, the screeningbeing held in a stretched position by tightening of the screw 42 in bracket M.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claim.

Having described the invention, what is claimed as new is:

A window construction including a window frame having upper and lower sliding sash therein, each sash including a frame having vertical grooves at its sides, resilient channel shaped guides in the window frame having a pair of parallel flanges and a connecting rib for the flanges, inwardly extended opposed lips on the edges of the flanges engaged in the grooves of the sash, and friction gripping adjusting means for the opposed lips of the guides, said friction gripping adjusting means comprising a longitudinal convexed web portion for the guide, and screws passing through the web portion of the guides and threaded into the window frame to move the opposed lips of the guide relative to each other.
